Between Chuck and Flight of the Conchords, The Big Bang Theory and Tina Fey's 30 Rock alter ego Liz Lemon, I'm not sure we needed any more proof that we're in something of a pop culture nerd renaissance right now. But just in case, here's something else: The guy who wrote Fanboys just had another script picked up, this time about "a video game junkie facing a midlife crisis who learns that a young punk had broken a record he set as a teen." The guy sets out to reclaim his position at the top of the gaming throne. Nerd power!

That got me thinking about some of my favorite on-screen nerds — from the aforementioned Liz Lemon and Conchords guys to more classic outsiders like My So-Called Life's Brian Krakow (and his volumeter) and Patrick Dempsey's Ronald from Can't Buy Me Love. So now I'm wondering: Who are yours? For the purposes of this conversation, let's assume that "nerd" and "geek" mean approximately the same thing, though of course we could debate the distinctions for days . . .
